North Carolina Democrat David Price was a junior staff member at the time, and wrote in his book "The Congressional Experience" that the moment could not have been more dramatic.
"It was a moment capable of convincing a young person that the system worked, that enough dedicated people, working together, could right ancient wrongs," wrote Price on Engle's appearance.
In May of 1985, Republican Sen. Pete Wilson was wheeled onto the floor to vote for the Senate's budget resolution following an appendectomy.

Confined to a wheelchair, Democratic Senator Robert Byrd showed up to vote for what was important to him throughout the year prior to his death in June 2010 from heat exhaustion, reported ABC News.

At 92, Byrd died as the longest-serving member of Congress at the time.

According to CNN, Wyden returned to the Senate to vote on the START treaty just two days after surgery.
